I of guide lugs 4 which cooperate with the side ing at St. Louis, Missouri, have invented it? being had to the occompanyinp drawings,

forming part of this specification, in which Figure 1.is a side elevotional view of a portion of a car truck constructed in accordance with my invention; and Fig 2 is a top plan view thereof.

This invention relates to new and useful improvements in car trucks.

. A car truck of the type herein shown and described is provided with side frames hoving bolster-receiving openings and columns which form the sides of said openings, the bolster being slidingly mounted between said columns.

csuse'tlie bolster to strike very severe hammer blows on the upper portion of the colulimia, and these hammer blows very often breaker crack said columns.

In accordance with my invention the upe reinforcing rib which projects into the bolster-receiving opening and receives the shocks 111st referred to.

which is provided with pairs of guide lugs adjacent its ends.

To remove the bolster from the truck the first step is to remove springs 5 and allow bolster to drop onto the spring seats 6. When the bolster is resting on the spring seats its guide lugs are out of elinernent with as (30 per portion of each column is prox-idcd with These ribs also serve as gu des for the bolster, and are adopted to cooperate with the stundurd type of bolster truck as these elements form no 1 invention.

ribs 3, and it can be moved longitudinally through the openings in the side frames I do not deem it necessary to show or de scribe the wheels, journal boxes and various tie bars which are usually employed on it car so port of this i am aware that it is old to employ remova able keys which project into the bolsterreceiving 0 )ening and cooperate with the bolster guides, but these keys weaken the columns at the point where they receive the greatest stresses.
